IPC: H02P27/04
Filed: 1986-07-04
Abstract: PURPOSE:To suppress unstable elements such as generation of unnecessary forcing current and insufficiency of torque by providing a fixed field control if a speed feedback signal differs substantially from a speed standard on completion of acceleration and due to disturbance. CONSTITUTION:A speed feedback signal (c) and a speed standard signal (b) are inputted to a detector part 21 and a magnetic flux operation is performed by an operator part 22 to give magnetic flux phi (d) to a motor 23 to provide a fixed field control. If a speed feedback signal differs substantially from a speed standard on completion of acceleration and due to disturbance in an operation within a field strngthening region, the speed feedback signal and a base speed + alpha are compared with each other and a fixed field control is provided in the case of speed feedback signal <= base speed + alpha (f). Therefore, a field (h) is fixed and an insufficiency of torque and the like caused by weakening of magnetic flux are suppressed, because a field-weakening control is performed at the speed standard.

Title: Method and device for collecting peening material

IPC: B24C9/00
Filed: 1988-06-27
Abstract: PURPOSE:To treat products uniformly by sorting and removing peening material with minor particle sizes from the peening material used circulatively, taking out part of it, classifying into major particle sizes and minor particle sizes, calculating the weight ratio, comparing with the set value, altering the rate of flow of air stream on the basis of the result from comparison, changing the dispersed condition of the peening material, and making the weight ratio to the set value. CONSTITUTION:Collected peening material is allowed to fall naturally, and the peening material is dispersed horizontally by orthogonally intersecting the air stream to this falling peening material to generate penetrative flow, and thereby the peening material with minor particle sizes below a specified value is sorted and removed. Then part of the peening material is taken out of the collected peening material and classified into minor particle sizes and major particle sizes, which are stored in respective hoppers and weighed by a weight gauge 11, followed by computation of their weight ratio by a control device 15. This weight ratio is compared with the set value, and on the basis of result, a motor-driven damper 7 of a duct 6 is driven under control to alter the rate of flow of the air stream, and thus the dispersed condition of the peening material dispersed is changed so as to make the weight ratio identical to the set value, which accomplishes uniformly shot-peened products.
